Fetal Cerebrovascular Autoregulation in Congenital Heart Disease and Association With Neonatal Neurobehavior
Recruiting
Determine 1) the impact of abnormal fetal cerebrovascular physiology with neurodevelopmental delay (ND) outcomes and 2) how this relationship is modified by patient and environmental factors such as chronic congenital heart disease (CCHD) lesion, maternal-fetal environment, and social determinants of heath (SDOH) in a diverse population using a multicenter design. Pregnant women will be approached during one of their fetal cardiology clinic visits.

Study to Check the Safety of Fazirsiran and Learn if Fazirsiran Can Help People With Liver Disease and Scarring (Fibrosis) Due to an Abnormal Version of Alpha-1 Antitrypsin Protein
Recruiting
The main aim of this study is to learn if fazirsiran reduces liver scarring (fibrosis) compared to placebo. Other aims are to learn if fazirsiran slows down the disease worsening in the liver, to get information on how fazirsiran affects the body (called pharmacodynamics), to learn if fazirsiran reduces other liver injury (inflammation) and the abnormal Z-AAT protein in the liver, to get information on how the body processes fazirsiran (called pharmacokinetics), to test how well fazirsiran works...

The Patient and Family Centered I-PASS LISTEN Study: Language, Inclusion, Safety, and Teamwork for Equity Now
Recruiting
In 2014, a team of parents, nurses, and physicians created Patient and Family Centered I-PASS (PFC I-PASS), a bundle of communication interventions to improve the quality of information exchange between physicians, nurses, and families, and to better integrate families into all aspects of daily decision making in hospitals. PFC I-PASS changed how doctors and nurses talk to patients and families on rounds when they're admitted to the hospital. (Rounds are when a team of doctors visit patients eve... Read More
